Tractive effort is the force generated by a vehicle's engine or motor in order to generate motion through tractive force. Tractive effort differs from tractive force, which is the actual force applied at the road surface, by the amount of rolling resistance present. In mathematical terms,

Tractive Effort = Tractive Force + Rolling Resistance.

Tractive effort is a function of vehicle speed and can refer to tractive effort available or tractive effort required:

Tractive effort available: maximum tractive effort of a vehicle as limited by the available power (or at low speeds, friction).

Tractive effort required: the amount of tractive effort required to overcome the resistive forces caused by rolling resistance, air resistance, grade, and/or drawbar pull.

@Lucky

The Tractive effort is not as you said.

It is the force available at the driving wheels and it is not torque at all.

Tractive force= Engine torque*Gear Ratio*Final drive/ Wheel Radius

Tractive effort is defined as the force at the rims or the outer edges of the driving wheels of moving trains.

Tractive effort means actual force applied at the road surface, by the amount of rolling resistance present.

What is a tractive effort? Can you tell me, I couldn't understand it ?

It's the clear description of tractive effort.

T = Weight X coefficient of friction.
